Unable to view the details of the volume snapshot

[Vincent Hou]

When I click a volume snapshot created from a volume, it directs me to a page with error message. Please refer to the picture.

[Gabriel Hurley (gabriel-hurley)]

This indicates that an error occurred in novaclient/cinderclient while trying to fetch the volume in the view. Without the error logs there's no way to debug this issue.

Hi Gabriel. I am using devstack and the code is from the master. I have been aware of what you say, but there is no error message from the logs provided by devstack script. Could you tell me how to check the log of novaclient/cinderclient in devstack environment?

Hi Vincent,

By default devstack does not log to files ... instead, it logs to the screen session's window for the project. So, if you do:

screen -x

You should be able to see all the OpenStack services in different screen windows... though you will only be able to see the last screen of information and not able to scroll back.

To enable file-based logging with devstack, you can set the:

SCREEN_LOGDIR = /path/to/some/dir

option in your localrc file and then run stack.sh again. The services will then also get logged to files in that directory.

Best,
-jay

Thank you so much, Jay. I will try it.

This is the log I received for clicking a snapshot. Horizon was supposed to look for the snapshot, but it tried to get the volume. Please take a look at it.

That's trying to link to a "detail" page for the volume snapshot, which is not implemented. It's a carryover from the base table it inherits from there.

    Rollup of volume fixes.

      * Standardizes volume attachment wording.
      * Defensive coding for missing values in attachment dict.
        Fixes bug 1004412 and bug 1004337.
      * Adds polling to Snapshots and Volume Snapshots tables.
        Fixes bug 1005805.
      * Removes an erroneous link on the Volume Snapshots table.
        Fixes bug 1005806.
      * Correts the "type" property on the Images and Snapshots tables.
        Fixes bug 1011910.

    This seems to restore all supported functionality related to volumes using
    devstack master.
